A New Energy-Efficient Hydrogel Pulls Water From Air

Cars That Think

Using a new kind of hydrogel material, researchers at the University of Texas at Austin have pulled water out of thin air at temperatures low enough to be achieved with sunlight. Atmospheric water harvesting draws water from humidity in the air. The material is a hydrogel, a polymer network that naturally retains a lot of water.

Israeli team develops decoupled PEC water-splitting system for centralized production of H2

Green Car Congress

Researchers in Israel have designed a separate-cell photoelectrochemical (PEC) water-splitting system with decoupled hydrogen and oxygen cells for centralized hydrogen production. A paper describing their system is publishedin the journal Joule. The hydrogen cell contains the cathode, and it is physically separated from the oxygen cell.

Rice U team creates low-cost, high-efficiency integrated device for solar-driven water splitting; solar leaf

Green Car Congress

Rice University researchers have created an efficient, low-cost device that splits water to produce hydrogen fuel. The current flows to the catalysts that turn water into hydrogen and oxygen, with a sunlight-to-hydrogen efficiency as high as 6.7%. It utilizes water and sunlight to get chemical fuels.
